Documented Uses

• A plant growth regulator used as a growth retardant
• Plant growth regulator synthesis and function inhibitor
• Plant growth regulator and defoliant with the properties of an antiauxin
• ... 2-aminobenzoic acid with iodine monochloride to form 2-amino-3,5-diiodobenzoic acid ... diazotized and reacted with potassium to yield 2,3,5-triiodobenzoic acid
• Benzoic acid, 2,3,5-triiodo-: ACTIVE
• Rats receiving oral doses of C14-carboxyl or 2,3( 125-I),5(125-I)-triiodobenzoic acid excreted 72-75% of the radioactivity in urine and 24-28% in feces during the 4 days following drug administration. Peak levels of carbon-14 were observed in brain, thyroid, liver, lungs, heart, spleen, kidneys, and carcass 4 or 8 hr after dosing and rapidly decreased thereafter. Levels of iodine-125 were significantly higher than carbon-14 levels in the brain and thyroid. Iodine-125 in thyroid increased with time. ...
